The current is going through two silicon diodes though, with attendant .5 volt drop through each so consider if that will be a problem in this application. Likely its not. (...) Tom Napolitano tomnap@bersama.net (22 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)

(...) I'd be a little surprised at a bridge rectifier which couldn't accept DC. Many electronic appliances have them these days so that it doesn't really matter what kind of wall wart you use, so long as the voltage is in the right range. The wall (...)

I think you misuderstood what Larry said (or I misunderstood what you said). I think Larry was saying that you should use the wall wart from the train speed regulator, which is what Lego recommends. Also, I dont see how you could burn out the diodes (...) (22 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)

(...) You can do this but it's not recommended. As the RCX 1.0 has a bridge rectifier on the power input, it's recommended you use a 10v AC supply, to avoid buring out the diodes. ROSCO (22 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)
